Experts Talks
We all know the importance of hand hygiene. However, when we have dry, damaged hands, frequent washing can cause irritation on the hands. It is important to understand how our skin works in order to take care of it.
Repeated washing and weather conditions like the cold, when experienced daily, can often provoke or aggravate dry skin on hands. The skin feels tight, stings and turns red. It can therefore be difficult to combine disinfection and nourishment.
Experts in dermatology, Laboratoire Bioderma has innovated by developing a unique 2-in-1 product. It is specially adapted to meet the needs of skin on hands that is prone to dryness.
Biphase Lipo alcoolique is therefore neither a traditional hydroalcoholic gel, nor a simple disinfecting gel that moisturises. It’s a product that nourishes and disinfects, containing both fatty substances to nourish skin and alcohol to disinfect perfectly.

Some ingredients, like aloe vera or glycerin, are known to hydrate the skin. If your hands are dry from repeated washing, they provide water to compensate.
However, they have no effect on the cause of this drying. It a bit like filling a colander with water – it stays wet but doesn’t hold any of the water.
Providing lipids (fatty substances) enables the skin to restore its barrier function by rebuilding its hydrolipidic film and intercellular cement.
The skin maintains its natural protection and is better at retaining the water – preventing the skin from drying out.
Biphase Lipo alcoolique, our nourishing hand sanitizer, uses biomimicking lipids inspired by the skin’s biology:
Squalane promotes the natural production of epidermal lipids involved in hydration. It helps to maintain water and thus make the skin less dry, providing instant and lasting comfort.
Shea oil reinforces the skin's protective film and the structure of the epidermis by adding lipids. The skin is nourished, soft and soothed.
Together, the intercellular cement and hydrolipic film enable the skin to carry out its barrier function:
1) Prevent allergens, pollution and other external toxic elements from entering the skin.
2) Prevent excessive water loss by reducing evaporation to maintain the barrier function.
Regularly washing your hands dissolves the skin’s lipids. The barrier function is therefore no longer effective, water loss increases, and the skin presents the signs characteristic of dry, very dry and fragile skin – from irritation to itching, burning sensations, cracking and splitting.
Our product, Biphase Lipo alcoolique is absorbed quickly into the skin with a soft, gentle sensation. And without leaving your hands feeling greasy or sticky. The skin is nourished every time and you can immediately carry on with all your activities.
The results of tests1 carried out under medical conditions revealed:
Biphase Lipo alcoolique has been proven to eliminate more than 99.9% of viruses, bacteria and yeasts.
It therefore has all three standards EN 13727, EN 14476 and EN 13624.
Biphase Lipo alcoolique has been shown to reduce hand dehydration compared to a hydro-alcoholic solution with glycerin, where glycerin is a moisturising agent. This means that Biphase Lipo alcoolique helps to restore the skin barrier: its limits water loss and thus skin dryness. A hydroalcoholic solution with glycerin does not allow this because this moisturising agent is not able to bring lipids to the skin and therefore restore the skin barrier.
This study was conducted under medical supervision on 20 volunteers who applied the product 10 times a day for 21 days (August 2020, France). The results of this study show that after using Biphase Lipo alcoolique, dehydration (water loss) was reduced by 22.6%. It therefore strengthens the skin barrier 2.5 times more than a hydro-alcoholic solution with glycerin.
Dehydration is measured with the so-called transepidermal water loss (TEWL).
The higher the TEWL (i.e. water loss), the greater the damage to the skin barrier and the more easily the skin loses water. On the other hand, the lower the TEWL (i.e. water loss), the more water the skin is able to retain and thus avoid dryness.
In our study, Biphase Lipo alcoolique has a TEWL of -22.6% while a hydro-alcoholic solution with glycerin has a TEWL of -6%. The water loss is therefore more important in the second case.
